Title: Copolymers of styrene and silane coupling agent, synthesizing method and method for improving adhesion performance in fiber-reinforced polystyrene composites by using the copolymers
Inventor: JEONG JONGKOO
IPC: C08L25/06
Filed: 1994-05-11
Abstract: Novel agents for improving adhesion performance between fibers and resins in fiber reinforced polystyrene composites and synthesizing method thereof and method for improving adhesion performance in fiber reinforced polystyrene composites by using the copolymers are disclosed. The agents are copolymers of styrene and silane coupling agents, and the copolymer can be manufactured by copolymerizing styrene monomer and silane coupling agents in benzene solvent at nitrogen atmosphere by employing azobisisobutyronitrile (AIBN) and the like as an initiator after purifying the reactants and eliminating polymerization inhibitor from the reactants. The typical copolymer is poly(styrene-co-.gamma.-MPS)(.gamma.-MPS means .gamma. -methacryloxypropyltrimethoxysilane) which is manufactured by copolymerizing styrene monomer and .gamma.-MPS. Adhesion performance of the polystyrene fiber composites is improved by hydrolyzing the copolymer in the presence of solvent and applying the copolymer to the surface of the fibers for reinforcing and then immersing the fibers into polystyrene resin composition after drying. Fiberglass materials are most preferably employed as fibers for reinforcing. Adhesion performance between the fibers and matrix resin is substantially improved, resulting in enhanced the strength and endurance of the composite.

Patent CA-2126957-A1 (CA)
Title: Drying nozzle
Inventor: FEYRER WOLFGANG
IPC: B05B9/01
Filed: 1994-06-28
Abstract: ABSTRACT           A drying nozzle is comprised of a tubular body (tube) for mounting on a nozzle head of a spray gun. The body contains inlet slits for ambient air entering one tube end which taper in a direction of the interior of the tube. The body expands toward the other tube end. Upon mounting the body on the nozzle head the narrowest region of the tube between the tapering region of the inlet slits and the expanding region of the tube lies directly behind an air outlet opening when seen in direction of flow of the air passing out of the air outlet opening of the nozzle head. Upon supplying compressed air in the center of the tubular body a negative pressure in the tube interior is produced and as a result of which ambient air is drawn into one tube end and passes out at the other tube end together with the compressed air.
Patent CA-2127514-A1 (CA)
Title: Autoclave
Inventor: STOKER PIETER W
IPC: B01J3/04
Filed: 1994-07-06
Abstract: An autoclave 10 has a first vessel 12 in which objects are heated, and a second vessel 14 in which the objects are cooled down.  A container 24 containing the objects is introduced via a preheating chamber 30 into a chamber 20, and thence into the cavity 16 of the vessel 12.  Similarly, at the downstream end of the second vessel 14, a container is removed from a cavity 18 via a chamber 22.  Transfer of containers is effected lock fashion to limit loss of pressure.  When a container is thus removed and a fresh container is loaded, containers in the cavity 16 are advanced upwardly and containers in the cavity 18 are advanced downwardly.  A container at the top of the cavity 16 is laterally displaced to the top of the cavity 18, via a chamber 19.  The autoclave is thus operated continuously, stepwise.  Pressures and temperatures are monitored via an interface 32 and a computer 34.          Sterilization values for the objects are computed and advance of the containers are dependant on appropriate sterilization values being obtained.

Title: Synchronous adder device
Inventor: HIRAMATSU KATSUHIKO
IPC: H04L27/26
Filed: 1994-10-04
Abstract: A synchronous adder device comprising an A/D converter for digitizing a receive signal transmitted through a plurality of subcarriers by sampling it and an adding unit for determining the value of synchronous addition for each sample is provided with synthetic waveform shaping filters for waveform-shaping every other subcarrier, squaring units for squaring the respective outputs of the synthetic waveform shaping filters, and a low pass filter for removing a harmonic components from the sum of outputs of the squaring units.  In the case where the signal is transmitted through four subcarriers, synchronous addition becomes possible by using the synthetic waveform shaping filters the number of which is two for each of an I signal and a Q signal or is four in total.  The number of squaring units equal to the number of synthetic waveform shaping filters suffices.  Though an output of the squaring unit includes an envelope component and harmonic components since the squaring unit squares signals of the plurality of subcarriers together, the harmonic components can be removed by the low pass filter, thereby making it possible to extract only the envelope component.

Title: Cultured taxu tissues as a source of taxol, related taxanes and other novel anti-tumor/anti-viral compounds
Inventor: ARTECA RICHARD N
IPC: A01H4/00
Filed: 1993-05-11
Abstract: Successful culture methods have been developed which result in stable, long-term tissue cultures derived from Taxus explants and hydroponically grown roots. These cultures offer a rapidly reproducible, continuously-available source for the production of purified taxol and taxol-related compounds. Culture methods include in vitro tissue culture and hydroponics. Cultures are initiated with stem or root tissues of Taxus or from roots grown hydroponically. Taxol production may be scaled to commercial levels by use of bioreactors. Screening assays are provided for species and cultures of Taxus that are sources of taxol and taxol-related compounds. In addition to obtaining the same compositions as presently directly extracted from yew trees, new compositions exhibiting taxol-like activity, have been purified from the novel Taxus sources, offering new horizons for chemotherapeutic agent development.

Title: Fence bracket
Inventor: LANDREVILLE CHARLES
IPC: E04H17/14
Filed: 1995-03-27
Abstract: The present  invention relates  to  a bracket  for mounting fence rails and other items to common rolled metal posts, including a flat front face and a rearwardly projecting apertured web.   Most commonly these are T-shaped in cross-section.   The bracket includes a front plate substantially wider than the front face of the post, two rear plates behind the front plate attached to the edges of the front plate, and two mounting plates projecting rearwardly from the edges of the rear  plates.     The  mounting  plates  have  apertures  in registration  with  each  other.    The  mounting  plates  are attachable to the apertured web to locate the front plate in abutting relationship with the front face of the post.  The front,  rear,  and mounting plates define a slot shaped to received the post.  The width of the front plate is sufficient to include apertures for fasteners to secure fencing members, which are not obstructed by the front face of the post.  A strap can be threaded through these apertures to secure a fence member.  The bracket is formed of stamped sheet metal bent to shape, or as a molded, cast, or extruded product.  An advantage of the present invention is that it can be used to secure various fence members including split rail, logs, sized lumber, cables, hoses or panels to common rolled metal posts.

Title: Table assembly for a conventional bench saw
Inventor: LETENDRE MICHEL
IPC: B23Q3/02
Filed: 1995-05-25
Abstract: A table assembly is described as a replacement for  the  work  supporting  table  forming  part  of  a conventional bench saw.   It includes a slidable panel having a longitudinal slot from which protrudes the upper portion of saw blades operatively mounted to the base of the bench saw.  The panel is equipped with an under frame which allows the panel to move in the longitudinal axis of the saw blades.  With this arrangement, a work piece placed on the top surface of the panel moves together with the panel during a good part of the sawing operation so that the front as well as the back support lengths are correspondingly increased whenever required with no need for  extra  floor  space.    Also,  the work  is  always subjected to identical friction forces on either side of the blades, whether the work is displaced with or on a supporting and movable surface, thus eliminating the need to secure the work piece to its supporting and movable panel prior to proceed with the cutting operation.
